Thanks for directing us to the web site for Japanese style chashu. I've also tried various styles looking for the right taste and texture similar to the ramen shop topping, and have not been happy with any of them until I saw the web page. Either I've been skipping steps or blind, it's the browning of meat before simmering that may do the trick. I've tried roasting, barbecuing, steaming, and simmering/braising alone, but never combined browning and simmering for making chashu. I do that when make American style pot roast.
